            Bug ID: 98237
           Summary: gcc-dg-lto-modref-3-01.exe etc. FAIL
           Product: gcc
           Version: 11.0
            Status: UNCONFIRMED
          Severity: normal
          Priority: P3
         Component: ipa
          Assignee: unassigned at gcc dot gnu.org
          Reporter: ro at gcc dot gnu.org
                CC: hubicka at gcc dot gnu.org, marxin at gcc dot gnu.org
  Target Milestone: ---

Two new ipa-modref tests FAIL since they were installed:

FAIL: gcc-dg-lto-modref-3-01.exe scan-wpa-ipa-dump modref "parm 1 flags:
nodirectescape"
FAIL: gcc-dg-lto-modref-4-01.exe scan-wpa-ipa-dump modref "parm 1 flags:
nodirectescape"

I'm seeing this on Solaris/sparc and x86, there are also gcc-testresults
reports
for hppa64-hp-hpux11.11.  However, this is not an OS issue at all: on Solaris
with GNU ld, the tests PASS, while they FAIL on x86_64-pc-linux-gnu with
--disable-lto-plugin.

    testsuite: Require lto-plugin support in gcc.dg/lto/modref-3 etc. [PR98237]

    gcc.dg/lto/modref-3 etc. FAIL on Solaris with the native linker:

    FAIL: gcc-dg-lto-modref-3-01.exe scan-wpa-ipa-dump modref "parm 1 flags:
no_direct_clobber no_direct_escape"
    FAIL: gcc-dg-lto-modref-4-01.exe scan-wpa-ipa-dump modref "parm 1 flags:
no_direct_clobber no_direct_escape"
    FAIL: gcc.dg/lto/modref-3 c_lto_modref-3_0.o-c_lto_modref-3_1.o execute -O2
-flto-partition=max -fdump-ipa-modref -fno-ipa-sra -fno-ipa-cp -flto
    FAIL: gcc.dg/lto/modref-4 c_lto_modref-4_0.o-c_lto_modref-4_1.o execute -O2
-flto-partition=max -fdump-ipa-modref -fno-ipa-sra -flto

    The issue is that the tests require the linker plugin, which isn't
    available with Solaris ld.  Thus, it also FAILs when gcc is configured
    with --disable-lto-plugin.

    This patch thus declares the requirement.  As it turns out, there's an
    undocumented dg-require-linker-plugin already, but I introduce and use
    the corresponding effective-target keyword and document both.

    Given that the effective-target form is more flexible, I'm tempted to
    remove dg-require-* with an empty arg as already mentioned in
    sourcebuild.texi.  That is not this patch, however.

    Tested on i386-pc-solaris2.11 with ld and gld.
